SS Invicta

Invicta was a passenger ferry built in 1939 for the Southern Railway and requisitioned on completion by the Admiralty for use as a troopship, serving in the Second World War as HMS Invicta. She was returned to the Southern Railway in 1945 and passed to British Railways in 1948. With the introduction to TOPS (a new numbering system) in 1968, Invicta was one of 14 "locomotives" classified as Class 99. She was allocated TOPS Number 99 010. Invicta served on the Dover – Calais route from 1946 until 1972 when she was withdrawn from service and scrapped.
